Disabling (Quiescing) an Application

Before you undeploy a web application, you want to the application to
complete serving requests. The process of gracefully disabling an application is called
quiescing. When you quiesce an application, you specify a timeout period. Based on
the timeout period, the load balancer uses the following policy for quiescing applications:

If the timeout has not expired, the load balancer does not forward
new requests to the application, but returns them to the web server. However, the
load balancer continues to forward sticky requests until the timeout expires.

When the timeout expires, the load balancer does not accept any requests
for the application, including sticky requests.

When you disable an application
from every server instance or cluster the load balancer references, the users of the
disabled application experience loss of service until the application is enabled again.
If you disable the application from one server instance or cluster while keeping it
enabled in another server instance or cluster, users can still access the application.
